LAN D-ROLLER.

SPECIFICATION forming part of Letters Patent No. 699,694, dated 13, 1902.

Application filed September '7, 1901. Serial No. 74,658. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES K. LONGEN- ECKER, a citizen of the United States, residing at Brooklyn, in the county ofKings, State of New York, have invented certain'new and useful Improvements in Land Rollers, of which the following is a specification.

' The purpose of this invention is to provide a land-roller suitable for rolling lawns, golfcourses, and the like in which the ends or corner portions of the roller are formed so as to prevent cutting or scoring of the land.

The invention comprises a roller having a cylindrical face or tread and a pair of heads I 5 united thereto by hollow flanges or cornerportions which curve gradually away from the cylindrical part of the roller, the arrangement being such as to give the required curvature and rigidity with a minimum amount of metal.

In rolling land, particularly with steamrollers which are quite heavy, the ordinary roller having angular ends or corners scores the land, especially where the earth is soft or where the roller is tilted by an obstruction which raises the roller at one end and from various other causes in the operation of the roller. In the use of the roller constructed according to the present invention these difficulties are avoided.

In the accompanying drawings, Figure 1 is a view, partly in side elevation and partly in central section, through a roller embodying the invention. Fig. 2 is an enlarged sectional View through one corner of the roller shown 3 5 in Fig. 1, illustrating the manner in which the corner portion is attached to the roller, and

Figs. 3, at, 5, and 6 are similar views showing the corner portions connected to the roller in various ways.

Referring to Figs. 1 and 2 of the drawings,

a indicates the cylindrical portion or face of the roller, and 1) indicates one of a pair of heads which are secured at opposite'ends of the roller-shaft c. To one of the headsbis se cured the usual driving-gear d. The cylinder a. is connected to the opposite heads b by the hollow flanges or corner portions 6, which, as shown, project laterally outward from the disk-like heads I) and thence curve inwardly to the cylinder a, the outer face of the corner portions being flush with the outer face of the cylinder. The depth of the flange between the inner wall 1 and the outer wall 2 is sufficient to provide a gradually-curved face 3 of sufficient depth to prevent the roller from cut- 5 5 ting into the sod. The edge 4 of the flange is thickened and recessed upon its outer face, as shown, to provide a bearing-surface for the cylinder a, which fits into this recess and forms aflush butt-joint 5 with the outer face of the flange. The cylinder is secured to the flange by rivets 6, passing through the cylinder, and the part 4., which underlies and supports the cylinder. The inner part 7 of the flange is likewise recessed upon its outer side, and the head I), fitting into said recess, forms a butt-joint 8 with the flange, being secured thereto by rivets 9. It will be seen that with this construction the butt-joints will take up the lateral and vertical stress, and the rivets will not be subjected to a shearing pressure. At suitable intervals the hollow flanges are braced radially by ribs 10, which are cast integral with the flanges. The flanges or corner portions are cast, and the heads and cylinder may, if desired, be of rolled metal.

In Fig. 3 a construction is shown in which the curved flange e is formed integral with the head I) and is connected with the cylinder at by rivets in the same manner as illustrated So in Figs. 1 and 2. In this construction the head is cast integral with the flange and the ribs 10.

In Fig. 4 the cylinder a is castintegral with the flange, and the head I) is connected to the flange by rivets.

Fig. 5 shows one corner of a roller in which the cylindrical portion a and the heads 12 are integral with the flanges, the roller being cast in one piece. I o

In Fig. 6 the head I) 3 has an inwardly-turned flange 11, which extends partially within the cylinder a and is connected thereto by rivets 12, and the flange e, which may be of rolled or cast metal, is secured by rivets 13 to the outer side of the head and by rivets 14 to the face of the flange 11, the outer end of the flange e resting upon the flange 11 and abutting agaiust the end of the cylinder a, makinga flush butt-joint 15. In this instance the too hollow flange is braced by the head If and the ribs may be omitted.

On account of the construction shown it will be readily understood that the ends of the roller cannot in operation cut into the land. The hollow projecting flanges admit of long curved surfaces without necessitating an excessive amount of metal.

It is preferred to form the flanges separate from the heads and cylinder, as shown in Figs. 1 and 2; but the roller may be made in any of the forms shown, the flanges being cast integral with the cylinder and riveted to the heads or cast integral with the heads and riveted to the cylinder,or the entire roller may be cast in one piece.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A land-roller having a cylindrical face, a pair of heads and hollow annular flanges uniting the face with the heads, said flanges proj ectin g laterally outward beyond the heads and curving inwardly to the face of the roller.

2. A land-roller comprising a cylindrical face, a pair of heads, and hollow annular flanges uniting the face with the heads, said flanges projecting laterally outward beyond the heads and curving inwardly to the face of the roller, and having internal ribs arranged to brace the flanges radially.

'3. A land-roller comprising a cylindrical face-plate, and a pair of heads secured there- 'to by hollow flanges, said flanges extending laterally outward from the heads and curving inwardly to the face-plate and being united to said plate by a flush joint.

4. A land-roller comprising a cylindrical face-plate and a pair of heads secured thereto by radially-braced hollow flanges, said flanges extending laterally outward from the heads and curving inwardly to the face-plate and being united to the face-plate by a flush joint.

5. A land-roller comprising a cylindrical face-plate, a pair of heads and separate hollow flanges secured to the heads and faceplate, said flanges projecting laterally outward beyond the heads and curving inwardly to the face-plate, and being secured to said plate by a flush joint.

6. A land-roller comprising a cylindrical face-plate, a pair of heads and separate hollow flanges secured to the heads and faceplate, said flanges projecting laterally out-- ward beyond the heads and curving inwardly to the face-plate and making a flushjoint therewith, and said flanges having internal ribs arranged to brace them radially.

In testimony whereof I aflix my signature in presence of two witnesses.
